Virtual Reality, a Design Methodology WORKSHOP SUMMARY and OBSERVATIONS Virtual Reality, A Design Methodology WORKSHOP SUMMARY AND OBSERVATIONS Dan Neubauer 1/ Pete Evans 2/ Verena Paepcke-Hjeltness 3/ Betsy Barnhart 4 Iowa State University Department of Industrial Design (1234) [email protected] 1/ [email protected] 2/ [email protected] 3/ [email protected] 4 1. INTRODUCTION Empathy is at the core of human centered design and design thinking. Being able to put oneself into someone else’s shoes, truly immersing into the subject matter, discovering the actual issues to be solved is crucial to successful problem finding and problem solving. Educators aim to provide an educational environment that fosters empathy for diverse environments including environments where access to people and contexts is restricted, limited, or too distant. The research team proposes emerging technologies, such as virtual reality (VR), as a supportive tool for creating empathy for the users and environments people are designing for. The goal is to empower design students with new design methodologies driven by VR to best identify and frame problems to be solved, understand the context and situation, and find the right design solutions in a highly technological and evermore complex world. Therefore, Virtual Reality as a Design Research Methodology was implemented in a workshop framework to provide the opportunity for a diverse group of students in Industrial Design to come together and test the novel role of virtual reality in the creation of empathy in the front end of the design process. The objective was to give students an opportunity to experience virtual reality as a design research method in order to improve both the level of empathy developed by the designer for the end user, and test different types of media to be used for virtual reality experiences. Virtual reality experiences might have the potential to generate research results and designs that are better honed to end user’s needs, and of more reliable quality. The findings of the workshop have potentially wide ranging implications for design research in particular and design education in general. Designers are continuously looking for new methodologies to develop a stronger sense of empathy with their end user; ultimately designing more meaningful experiences for the users. Historically this often requires many site visits, interviews, and detailed documentation of the scenario. These data points are then relied upon throughout the design process to inform the final solution and outcomes. By utilizing Virtual Reality tools and techniques, the designer will be able to “put themselves in another’s shoes”. More closely identifying with the end user, the user’s struggles, and the problems they face. Virtual Reality is in the midst of a re-emergence in current day entertainment and experiences. As technology and materials have become more accessible, the cost and proliferation of VR capable devices has grown exponentially over the last decade. Therefore, the research team constructed an experimental design charrette (workshop) in which to test the possibilities of implementing Virtual Reality experiences in the front end stages of design and design research. The workshop allowed the researchers the opportunity to begin to answer some of these questions: How do we connect with spaces and people with limited or restricted access? How do we design for a situation we have not experienced? How do we develop true empathy for challenges of unprecedented magnitude? 2. WORKSHOP SUMMARY The virtual reality workshop was provided in (2) three-hour sessions for 86 industrial design students ranging from sophomores to seniors attending college. The workshop began with a short introduction of the overall objectives to be tested and the environment the participants would be designing for. The virtual environment of focus for the workshop was the International Space Station (ISS). The selection was made based upon the idea that the ISS is an environment that cannot be accessed through what might be considered normal means of design research methodologies and data collection. Participants/Students in the first session were challenged to design personal hygiene solutions for micro- gravity aboard the ISS. The second session was divided in two, where one group was similarly challenged to design for personal hygiene, while the other group was challenged to design for injury avoidance aboard the ISS. With the help of contemporary media sources and a collaboration with an aerospace engineering PhD student researching Virtual Reality applications, the workshop utilized a virtual reality simulation model of the International Space Station, and 360-degree video footage of the International Space Station recorded by astronauts while aboard the station. With these two options for a virtual experience of the space station the workshop would offer students varying levels of “presence” in the space. Presence is an internal psychological state and a form of visceral communication (Jerald, 2015) The varied levels of presence would also offer the research group the opportunity to test two types of media and how those could help the viewer/designer develop empathy for the end user. Figure 1: Research Group visual breakdown In an effort to create control groups, students were divided into three research groups. Each group was provided a varying level of presence or immersion into the problem space. All groups had access to the traditional research packet (revolving around injury prevention and hygiene issues aboard the ISS), internet, and an ISS expert. The first group was allowed only the traditional methods of research. The second group was provided the same research packet, interview, and a 360-degree video tour of the international space station. These students were then able to view the tour through a low cost VR viewing headset (Google cardboard™). The third and final group was provided the same research packet and interview as the other groups; along with an immersive ISS simulation experience that was accessed through the Oculus Rift and HTC Vive head mounted VR displays. All of the groups had the same amount of time for research and were given the opportunity to leverage the different experiences along with the research packet to help them identify the problem’s context more fully. After the students researched and explored the problem space they were provided a worksheet in which to begin to “place” and formulate their opportunities for innovation. Each group then had one hour to ideate and refer back to either their research or their experience with either of the ISS simulations. Figure 2: Workshop Worksheet for Participants 3. VARIABLES IDENTIFIED INFLUENCING THE WORKSHOP OUTCOMES There were a number of variables that contributed to the workshop outcomes, and it is still to be seen if there is a positive or negative association with any or all of the variables. These variables include: • Inconsistency of the question answer session with the aerospace engineering PhD student • The time of day the workshops were run – session 1 was run in the morning session, session w was run in the afternoon • The spaces in which the participants were working- open air vs closed spaces • The learning curve and acclimation that is required for the VR head mounted displays • Use of internet as another research resource 4. OBSERVATIONS AND OUTCOMES Overall, the final concept solution drawings to the design challenges of the workshop were underwhelming. There was no strong differentiation between the different experiences of research methods, when examining the final concept outcomes. However, when looking at the problem statement and identification stages of the workshop, some observations can be made. One observation made after reviewing the group worksheets, is that in nearly every case of VR exposure, both 360 video and the simulation, the participants clearly described zero gravity or low gravity as one of the main concerns in the problem definition stage. In contrast, the traditional research packet teams did not make the same explicit mention of the problem space. An inference can be made, due to the exposure of VR, the participants were faced with a zero gravity or micro-gravity experience, and therefore made it a point to identify that as a critical component to the problem space. Another assumption can be made, that the traditional research packet teams, while they were aware of the problem of zero gravity, their omission of this component to the worksheets was due to inexperience, or making Figure 3: Workshop outcomes the assumption that viewers would know they were designing for zero gravity. Historically, these assumptions are commonly made by design students, and can lead to poor final results in their projects. When contrasting final concepts of the VR groups to the traditional groups, there seems to be a higher level of technicality to the concepts of the traditional research groups. Is this a product of the technical articles and data that were provided to them? Why, if the VR groups were provided the same materials and the addition of VR, might the concepts not be at a similar level of complexity and technicality? Could the students have been overwhelmed with the new experience and not provided enough time to digest the experience in order to leverage it as design research? Lastly, while exposing participants to the VR simulation experience, it was observed that there is a strong learning curve for navigation of the VR space. Controllers and identifiers within the simulation may not be intuitive enough at their present level of development. More exploration with these components is necessary for a better study. Further investigation of the outcomes of these experiences with VR is needed to develop the technology as a viable design research methodology. 5. NEXT STEPS After completing the workshop and reflecting upon its outcomes, there are many more questions that need to be explored in this area to claim that Virtual Reality can be used effectively as a design research methodology.

    JACKSON: CHOOSING A METHODOLOGY: PHILOSOPHICAL UNDERPINNING Choosing a Methodology: Philosophical Practitioner Research Underpinning In Higher Education Copyright © 2013 University of Cumbria Vol 7 (1) pages 49-62 Elizabeth Jackson University of Cumbria [email protected] Abstract As a university lecturer, I find that a frequent question raised by Masters students concerns the methodology chosen for research and the rationale required in dissertations. This paper unpicks some of the philosophical coherence that can inform choices to be made regarding methodology and a well-thought out rationale that can add to the rigour of a research project. It considers the conceptual framework for research including the ontological and epistemological perspectives that are pertinent in choosing a methodology and subsequently the methods to be used. The discussion is exemplified using a concrete example of a research project in order to contextualise theory within practice. Key words Ontology; epistemology; positionality; relationality; methodology; method. Introduction This paper arises from work with students writing Masters dissertations who frequently express confusion and doubt about how appropriate methodology is chosen for research. It will be argued here that consideration of philosophical underpinning can be crucial for both shaping research design and for explaining approaches taken in order to support credibility of research outcomes. It is beneficial, within the unique context of the research, for the researcher to carefully

  • On Becoming a Pragmatic Researcher: the Importance of Combining Quantitative and Qualitative Research Methodologies
    DOCUMENT RESUME ED 482 462 TM 035 389 AUTHOR Onwuegbuzie, Anthony J.; Leech, Nancy L. TITLE On Becoming a Pragmatic Researcher: The Importance of Combining Quantitative and Qualitative Research Methodologies. PUB DATE 2003-11-00 NOTE 25p.; Paper presented at the Annual Meeting of the Mid-South Educational Research Association (Biloxi, MS, November 5-7, 2003). PUB TYPE Reports Descriptive (141) Speeches/Meeting Papers (150) EDRS PRICE EDRS Price MF01/PCO2 Plus Postage. DESCRIPTORS *Pragmatics; *Qualitative Research; *Research Methodology; *Researchers ABSTRACT The last 100 years have witnessed a fervent debate in the United States about quantitative and qualitative research paradigms. Unfortunately, this has led to a great divide between quantitative and qualitative researchers, who often view themselves in competition with each other. Clearly, this polarization has promoted purists, i.e., researchers who restrict themselves exclusively to either quantitative or qualitative research methods. Mono-method research is the biggest threat to the advancement of the social sciences. As long as researchers stay polarized in research they cannot expect stakeholders who rely on their research findings to take their work seriously. The purpose of this paper is to explore how the debate between quantitative and qualitative is divisive, and thus counterproductive for advancing the social and behavioral science field. This paper advocates that all graduate students learn to use and appreciate both quantitative and qualitative research. In so doing, students will develop into what is termed "pragmatic researchers."

  • An Invitation to Qualitative Research
    CHAPTER 1 An Invitation to Qualitative Research n recent years, binge drinking has caused considerable concern among admin - istrators at colleges and universities, compelled by statistics that show marked Iincreases in such behavior. A qualitative researcher studying this topic would seek to go behind the statistics to understand the issue. Recently, we attended a fac - ulty meeting that addressed the problem of binge drinking and heard concerned faculty and administrators suggest some of the following solutions: • stricter campus policies with enforced consequences • more faculty-student socials with alcohol for those over 21 years old • more bus trips into the city to local sites such as major museums to get students interested in other pastimes Although well-intentioned, these folks were grasping at straws. This is because although they were armed with statistics indicating binge drinking was prevalent and thus could identify a problem, they had no information about why this trend was occurring. Without understanding this issue on a meaningful level, it is diffi - cult to remedy. At this point, we invite you to spend 5 to 10 minutes jotting down a list of questions you think are important to investigate as we try to better under - stand the phenomenon of binge drinking at college. What Is Qualitative Research? The qualitative approach to research is a unique grounding—the position from which to conduct research—that fosters particular ways of asking questions and particular ways of thinking through problems. As noted in the opening dis - cussion of binge drinking in college, the questions asked in this type of research usually begin with words like how, why, or what.

  • Internet Memes and Desensitization by Barbara Sanchez, University of Florida HSI Pathways to the Professoriate, Cohort 2
    VOLUME 1, ISSUE 2 Published January 2020 Internet Memes and Desensitization By Barbara Sanchez, University of Florida HSI Pathways to the Professoriate, Cohort 2 Abstract: Internet memes (IMs) have been used as a visual form of online rhetoric since the early 2000s. With hundreds of thousands now in circulation, IMs have become a prominent method of communication across the Internet. In this essay, I analyze the characteristics that have made IMs a mainstay in online communication. Understanding the definitions and structures of IMs aid in explaining their online success, especially on social platforms like Instagram, Facebook, and Twitter. I use these understandings as a basis from which to theorize how both the creative process in making IMs and the prominence of IMs that utilize images of originally violent or sensitive contexts may relate to existing research correlating violent media and desensitization. The use of these images often involves a disconnection from their original contexts in order to create a new and distinct— in many cases irrelevant— message and meaning. These IMs, in turn, exemplify the belittlement of distress depicted in such images—often for the sake of humor. This essay’s main goal is to propose a new theoretical lens from which to analyze the social and cultural influences on IMs. The greater purpose of this essay is not to devalue Internet memes nor to define them in narrow terms nor to claim there is any causal relationship between Internet memes and societal desensitization. Rather, I am proposing a new lens through which to further study Internet memes’ social effects on online users’ conceptions of violence and/or sensitive topics.

  • WRD Methodology
    Methodology of the World Religion Database Adapted from Todd M. Johnson and Brian J. Grim, The World’s Religions in Figures: An Introduction to International Religious Demography (Oxford: Wiley-Blackwell, 2013) The World Religion Database (WRD) is a dynamic online publication based on the research of the International Religious Demography Project, under the direction of Dr. Todd M. Johnson and Dr. Brian J. Grim, at Boston University’s Institute on Culture, Religion and World Affairs (CURA). The WRD collects, collates, and offers analyses of primary and secondary source material on demographic variables for all major religions in every country of the world. The database is unique in that it makes estimates from these sources readily available and fully transparent to the scholarly community. The WRD provides adherence data at the provincial level where available from censuses and surveys. It also aims to account for subgroups of each major religion to the maximum extent possible based on best social science and demographic practices. The right to profess one’s choice This methodology takes as its starting-point the United Nations 1948 Universal Declaration of Human Rights, Article 18: “Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief, and freedom, either alone or in community with others and in public or private, to manifest his religion or belief in teaching, practice, worship and observance.” Since its promulgation, this group of phrases has been incorporated into the state constitutions of a large number of countries across the world. This fundamental right also includes the right to claim the religion of one’s choice, and the right to be called a follower of that religion and to be enumerated as such.

    MEME WORLD SYNDROME: A CRITICAL DISCOURSE ANALYSIS OF THE FIRST WORLD PROBLEMS AND THIRD WORLD SUCCESS INTERNET MEMES by ROBERT CURRY CHANDLER B.A. Pepperdine University, 2008 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Arts in the Nicholson School of Communication in the College of Sciences at the University of Central Florida Orlando, Florida Summer Term 2013 © 2013 Robert Curry Chandler ii ABSTRACT This thesis applies the theory and method of Critical Discourse Analysis (CDA) to examine the ideological components of the First World Problems (FWP) and Third World Success (TWS) Internet memes. Drawing on analytical concepts from CDA and related perspectives, such as multimodal discourse analysis and social semiotics, the paper analyzes the visual and textual elements of a sample of the FWP and TWS memes. The paper argues that the text and images featured in the memes are ideologically salient and discursively construct oppositional binaries between “us” and “them” in terms of wealth disparity. iii TABLE OF CONTENTS LIST OF FIGURES .................................................................................................................................................. vi LIST OF TABLES................................................................................................................................................... vii CHAPTER ONE: INTRODUCTION .................................................................................................................... 1 CHAPTER

Copyright and re-use policy See http://shura.shu.ac.uk/information.html Sheffield Hallam University Research Archive http://shura.shu.ac.uk Title: An extra-memetic empirical methodology to accompany theoretical memetics Abstract Purpose: The paper describes the difficulties encountered by researchers who are looking to operationalise theoretical memetics and provides a methodological avenue for studies that can test meme theory. Design/Methodology/Approach: The application of evolutionary theory to organisations is reviewed by critically reflecting on the validity of its truth claims. To focus the discussion a number of applications of meme theory are reviewed to raise specific issues which ought to be the subject of empirical investigation. Subsequently, the empirical studies conducted to date are assessed in terms of the progress made and conclusions for further work are drawn. Findings: The paper finds that the key questions posed by memetic theory have yet to be addressed empirically and that a recurring weakness is the practice of assuming the existence of a replicating unit of culture which has, however, yet to be demonstrated as a valid concept. Therefore, an 'extra- memetic' methodology is deemed to be necessary for the development of memetics as a scientific endeavour.

  • A Systemic Definition of Methodology"
    Toward a Systemic Notion of Methodology: Practical Consequences and Pragmatic Importance of Including a Trivium and the Respective Ethos, Pathos, and Logos Nagib Callaos & Bekis Callaos Universidad Simón Bolívar and The International Institute of Informatics and Systemics (www.iiis.org) Unedited version (July 11, 2014) posted on the web in order to collect constructive feedback and criticism that will be addressed in the final version of this draft. Consequently no text of this draft is allowed to be cited without explicit assent of the author. Enquiries and Comment might be sent to ncallaos at att.net Abstract In spite of the increasing use of the term "methodology", its concept is frequently confused with that of "method", and, sometimes, it is hardly differentiated from that of "technique" or "tool". This situation of conceptual confusion is generating effects of undesirable practical incidence. Thus, a defining process of "methodology" and its related concepts could be of theoretical and practical interest. The objective of this paper is to make a first step in said defining process. Accordingly, we will try: (1) to identify different definitions of method and methodology, (2) to differentiate them and to relate them, between themselves, and with the concepts of "tool" and "technique"; and (3) by means of the definitions worked out, to differentiate between closed-efficient-systematic and opened-effective-systemic methodologies.1 We will differentiate between systemic and systematic methodologies and show the practical usefulness of this kind of distinction. We will also show that a systemic methodology necessarily contains cybernetic relationships between thinking/informing/knowing and doing, in the context of implicit or explicit meta- methodological processes of action-research, action-learning, and action-design.

  • Research Methodology
    Chapter Three: Research Methodology 3.1 Introduction The way in which research is conducted may be conceived of in terms of the research philosophy subscribed to, the research strategy employed and so the research instruments utilised (and perhaps developed) in the pursuit of a goal - the research objective(s) - and the quest for the solution of a problem - the research question. We have outlined our research question and research objectives in Chapter One. The purpose of this chapter is to: · discuss our research philosophy in relation to other philosophies; · expound our research strategy, including the research methodologies adopted; · introduce the research instruments that we have developed and utilised in the pursuit of our goals. 3.2 Research Philosophy A research philosophy is a belief about the way in which data about a phenomenon should be gathered, analysed and used. The term epistemology (what is known to be true) as opposed to doxology (what is believed to be true) encompasses the various philosophies of research approach. The purpose of science, then, is the process of transforming things believed into things known: doxa to episteme. Two major research philosophies have been identified in the Western tradition of science, namely positivist (sometimes called scientific) and interpretivist (also known as anti- positivist)(Galliers, 1991). 3.2.1 Positivism Positivists believe that reality is stable and can be observed and described from an objective viewpoint (Levin, 1988), i.e. without interfering with the phenomena being studied. They contend that phenomena should be isolated and that observations should be repeatable. This often involves manipulation of reality with variations in only a single independent variable so as to identify regularities in, and to form relationships between, some of the constituent elements of the social world.
